Feature Request - Drag and drop for file uploads

[Tyler_Sasaki]

The file management/file uploader in Shopify admin feature is extremely lacking. 

I'd like to request the following features:

• Drag and drop file uploading
• Sorting/filtering by file type
• Sorting by upload date
• Ability to rename uploaded files
• Ability to organize in a folder structure

Bump, this would be very useful
